1、同异频切换的参数配置A1事件:事件进入条件:Ms - Hys > Thresh停止异频测量门限:Threshold th2a for RSRP(Threshold2a) A1迟滞:Related hysteresis of threshold th2a for RSRP (hys threshold2a)服务小区的RSRP- hys threshold2a Threshold2a,且保持时间超过a1TimeToTriggerDeactInterMeas 的设置时间,则停止异频测量.A2事件:启动同频测量门限threshold1 事件进入条件:Ms + Hys Thresh 启动异频测量门
2、限:Threshold th2 interFreq for RSRP (threshold2InterFreq )A2迟滞:Related hysteresis of threshold th2 interfreq for RSRP(hysThreshold2InterFreq )打开Enable interfrequency handover:异频切换开关Time to trigger for A2 to activate inter measurement(a2TimeToTriggerActInterFreqMeas )当服务小区的RSRP+ hysThreshold2InterFreq
3、 < threshold2InterFreq,且保持时间超过的设置时间a2TimeToTriggerActInterFreqMeas ,则开始异频测量A3事件事件进入条件:Mn + Ofn + Ocn Hys > Ms + Ofs + Ocs + Off 事件离开条件:Mn + Ofn + Ocn + Hys < Ms + Ofs + Ocs + Off NSN无Ofn/Ocn/Ofs/Ocs 参数同频A3事件同频A3迟滞:Related hysteresis of offset a3offset for RSRP intra F(hysA3Offset )A3报告时长:A3
4、 report intervalA3触发时延:A3 time to triggerA3偏置:A3offset故同频A3事件需满足:邻小区的RSRPhysA3Offset >服务小区的RSRP+ a3Offset ,由于hysA3Offset配置为0,故A3事件的示意图如下图所示:异频A3事件异频A3偏置 A3 offset RSRP inter frequencya3OffsetRsrpInterFreq 异频A3报告时长:A3 report interval RSRP inter frequency异频A3触发时延:A3 time to trigger RSRP inter frequ
